AI Camera KOI Guide - 00 Introductions

AI Camera KOI is an offline Artificial Intelligence Module developed by Kittenbot. It is aimed to provide an easy to use platform for students and enthusiasts.KOI is an integrated module combining AI chip, camera, microphone, speaker, IPS display and Wifi chip into 1 convenient module.

AI Camera KOI has a lot of abilities, including Visual Recognition, Face Detection and Recognition, Object Classification, Speech Recognition and Text to Speech. With its built in Wifi chipset, you can even connect your KOI to the cloud for IoT AI Projects!

KOI’s functions can let you experience and learn Artificial Intelligence in a systematic way!

· Intended Audience:

STEM Education in Primary or Secondary Schools / STEM Enthusiasts / Advanced MakeCode or Kittenblock users

 

Features

      KOI Close Up

      Let’s take a closer look at the AI Camera KOI.

      Correct Orientation

      This is the default orientation of KOI.

      Camera Rotation

      The camera can be rotated from 0° to 180°. Be careful of the cable when rotating the camera.

       

      Front Camera Mode

      When both the camera and the display are facing towards you, the KOI is set up in Front Camera mode.

      This is usually used in face detection or visual recognition.

      Back Camera Mode

      Wehn the camera and the display are facing the opposite the direction, the KOI is set up in Back Camera mode.

      This is usually used in object classification, qr code/barcode recognition or line tracing.

      Display and Coordinates

      KOI uses an IPS display with a resolution of 240x240.

      The origin of the coordinates is at the top left corner with (x,y)=(0,0).

      Real time camera feed and system notifications will be displayed on the monitor.

      A & B and Reset Buttons

      2 programmable buttons are found on both sides of the KOI, they function like the A and B buttons found on the Micro:bit.

      A reset button is also found on the lower left hand side of the KOI, this is seldomly used.

      Microphone

      At the bottom left of the module, a microphone can be found. This microphone picks up sound in a range of approximately 50cm.

      PH2.0 4PIN Connector

      This connector handles the serial communication between KOI and other micro controllers.

      Pin out:

      LEGO Pin Connectors

      Round slots on the back of KOI are compatible with LEGO Technic pins.

      Pin Connector Spacing:

      Length: 4 spaces between pins

      Width: 3 spaces between pins
